It didn't. Off-hand, HanFree and Lockpicks by Open Locksport are both confirmed to have taken the money and run by the project creator, and ZionEyez and a whole bunch of others have simply gone silent.
The Open Locksport guy had a mental breakdown and the project has been taken over by new management and it seems like they're making (slow) progress now.
It seemed like one of the major issues with kickstarter, and I'm surprised they don't seem to have given it much thought.
